STOVE OR H EATIN SPECIFICATION forming part of Letters Application filedApril 22, 1398.

- heating=stoves, are frequently required to consume on occasion fromfive to ten times as large an amount of fuel as at other times. At thesame time such apparatus are expected to admit of being easily attendedto without requiring any special skill on the part of the attendant.

This invention has for its object to meet the above requirements, and ishereinafter de scribed with reference to the accompanying drawings, inwhich- Figure 1 is a vertical section of a stove constructed accordingto this invention; Fig; 2, a

horizontal section on line at a of Fig. 1; Fig. 3, a horizontal sectionon the line 3 y of Fig. 1. Fig. 4 is a plan view of one of the grates.

The heating apparatus comprises a fuel-receiver 1,provided with theusual bottom grate 2, ash-pit 3, feed-tube 4, and line 5. Upon oneportion of the fuel-receiver gratings 6, usually inclined, are soarranged that a continuous row of hollow spaces 7 is formed which spacesare separated from oneanother' partly or entirely, by thin layers offuel. The number of these hollow spaces or combustionchambers is equalto that of the gratings plus one. The first space or chamber is formedbetween the lowermost inclined grate 6 and the bottom grate 2, while thelastspace or chamber is formed above the topmost grate 6. The feed-tube4 may be constructed in the form of a cylindrical grate, as shown inFig. 1 in dotted lines. The remaining part of the fuel-receiver isconstructed as smoothly as possible, so as to enable the coals to easilydescend and so that, apart from the hollow spaces above referred to,-nofurther spaces or chambers are formed.

Patent No. 627,643, dated June 27, 1899.

SerialNo- 678,479. (No model.)

According to Fig. 1 each combustion-cham= her 7 may be provided with anair-valve 8-. When the coal or fuel is kindled upon the bottom grate,the gases are caused to traverse all the hollow spaces, thus heating thefuel within or in contact therewith, so that on subsequently opening theair-valves the fuel becomes ignited, whereby, if so desired, itscombustion may be obtained throughout the hollow spaces or chambers. Theheating-gases .Will always travel through the gratings instead ofpassing through the intermediate spaces formed between the fuelaccumulated in the fuel-receiver. Consequently the combustion will notmaterially extend into the fuel-column, so that the fuel serves as anef= ficien't medium for preventing the walls of the receiver from beingburned. By means of the air-valves the heating capacity of the stoveadmits of being varied within very wide limits, and the temperature canbe easily so regulated that the walls forming the combustionchambers arelikewise prevented from overheating.

The heating apparatus is especially suitable for burning fuel whichispoor in gas, in which case the produced gases are instantly consumedby the flames in the chamber 7, while the temperature, without attaininga degree such as to injurethe walls of the apparatus,

can be exactly-so adjusted that a complete combustion is obtained.

What I claim, and desire to secure by ters Patent, is.-

l A stove or heating apparatus comprising Letthe fuel-receiver 1, abottom grate 2, and a JESS ADOLPH JENSEN.
